My main interest is to understand how neuromodulatory transmitters regulate the function of brain circuits and influence sensory processing. Using the olfactory system as our model, we use a combination of electrophysiology, imaging, molecular biology techniques and behavior, to study how olfactory circuits are regulated by neuromodulators and how these signals shape olfactory processing and behavior. In humans, olfactory dysfunction is a characteristic early symptom in aging and several neurodegenerative disorders, therefore, our studies aim to understand pathological changes in olfactory circuits that occur in aging and neurodegeneration. Our research interests expand to other areas as well, through collaborations we are working on the development of novel technologies to study neuronal function and cell-based sensors, and to understand of mechanisms underlying the hypothalamic control of food consumption. In addition to research, a rewarding aspect of academic life is the teaching and training of young scientists. I have a firm commitment to excellence in mentoring and training of younger scientists, in particular under-represented groups in science fields. In the past years, I had the privilege of mentoring over 80 bright and promising undergraduates.
